(Granted under the act of"iMarch -;3, 1883, amended *April x30, 1928; 137:0 -1'0. G. H157) 'I'helpresent inventionrelates'to work tables. 7

Objects of thepresent invention aref toiprovide' an improved work table having a workz supporting surface which maybe both rotated and tilted; to provide such an improved work table, a

worksupporting surfaceof -which may be' sele'ctively secured in :aplur'ality of adjusted positions; to provide an improved construction and arrangements of elements in a device of the character described and for the purposes set forth; and to accomplish the above objects in a facile, economical and efficient manner.

In accomplishing these and other objects of the present invention, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawing, wherein:

Fig. 1 is a plan view of a work table embodying the features of the present invention and having a portion of the stationary table broken away to show the engagement of the disc and its associated latch;

Fig. 2 is a partial view in elevation of a work table embodying features of the present invention; and,

Fig. 3 is a reduced partial view in transverse section showing the engagement of the disc and its associated latch.

Referring more in detail to th drawing:

The stationary table I, has a U-shaped recess 2, formed therein. Two bearing sockets 3, are mounted on the stationary table on either side of said recess 2, and cooperate to rotatably mount a tubular support or shaft 4, extending across said recess 2. A bearing block 5, is secured to the support 4, at substantially the center of the recess 2. A circular work supporting member 6, having a work supporting surface, is disposed within said recess 2, and rotatably mounted in said bearing block 5, by means of a pintle 1, formed on said work supporting member 6, and journalled in said bearing block 5.

The work supporting member 6, is formed to provide a plurality of notches or interruptions 8. spaced about its periphery. A latch 9, is mount ed on the shaft 4, and has a spring [0, associated therewith for urging an arm H, of the latch 9, into engagement with the member 6. The latch 9, is also provided with a remote control, as the foot lever I2, and wire enclosed in a flexible cable represented at I3, for moving the latch 9, out of engagement with the member 6. The arm H, of the latch 9, is adapted to engage Within the notches or interruptions 8, of the work support 6," about an axis perpendicular to said member 'fi, at its center.

A partial disc A i"4,'= is 's'ecured "to the shaftor support -an'd "has notches --'or interruptions L1 5,

' spaced along itsa'rcuate periphery, similar to th'e notches*8,-of member fi. A latch 16," is mounted on thestationary table I and urgedinto engagement=withthe=dies f4,-"by-* a-spring -"l"l. "The latch IE, is also provided with a remote control including a foot lever I8, connected to the latch It, by a wire enclosed in a flexible cable represented at H]. The latch I6, is adapted to engage within the notches I5, of the partial disc I4, to restrain rotation of the shaft 4, and thereby restrain tilting of the member 6, by preventing said member 5, from rotating about the axis of the shaft 4.

The operation of a work table constructed as above described is as follows:

A work piece (not shown) upon which one or more operations are to be performed is placed upon the work supporting surface of the member 6. It is then adjusted to the position most advantageous, by adjusting the work table. This is accomplished by depressing the foot lever [2, which withdraws the latch 9, from its engagement with the work supporting member 6, thus permitting its free rotation until the foot lever I2, is released at which time the latch 9, is again urged against the member 6, by the action of the spring 10. The member 6, should then be turned until the arm H, of the latch 9, engages in the nearest notch 8, affording a positive engagement preventing further rotation of said member 6.

The foot lever I8, is then depressed, withdrawing the latch I6, from its engagement with the partial disc I 4, and permitting the tilting, or rotation of the work supporting member 6 about the axis of the tubular support or shaft 4. The foot lever I8, is then released and the latch I6, is again urged against the partial disc [4, by the action of the spring IT. The member 6, is then rotated a little more in the same direction, or a little in the opposit direction until the latch It, moves into a notch IE, on the partial disc 14 and thus affords a positive engagement preventing further tilting of the member 6, by restraining rotation of the shaft 4, to which the disc I4, is secured and upon which the work supporting member 6, is mounted by means of the pintle I, and the bearing block 5.

While I have shown but one embodiment of my invention, it is susceptible to modification without departing from the spirit of the invenmember 6, and restrain rotation of said member tion. I do not wish, herefore, to e l mi ed y porting member received in said recess, said member having a work supporting surface disposed substantially in a plane, and means mounting said member for rotation about an axis perpendicular to said surface and disposed centrally thereof and for rotation about a second axis perpendicular to said axis, said means including a shaft supported in said stationary table and rotatable about said second axis, a partial disc secured to said shaft and having a plurality of interruptions therein, a latch mounted on said stationary table and adapted to selectively engage said disc at said interruptions to maintain said shaft in a plurality of predetermined positions, a bearing block secured to said shaft, a pintle formed on said member and. journalled in said bearing block, said pintle mountin said member for rotation about the first mentioned axis, said member having a plurality of interruptions about its periphery, and a second latch mounted on said shaft and adapted to selectively engage said member at said interruptions and maintain said member in a plurality of predetermined positions.

WILLIAM 0. GILLY.
